Write the equation of the linear function that models the relationship shown in the table x 4 6 y 38 58

1 answer

To find the equation of the linear function that models the relationship between x and y in the table, we first need to find the slope (m) of the line. The slope can be found using the formula:

m = (y2 - y1) / (x2 - x1)

Using the points (4, 38) and (6, 58) from the table:

m = (58 - 38) / (6 - 4)
m = 20 / 2
m = 10

Next, we can use the point-slope form of a linear equation to write the equation of the line:

y - y1 = m(x - x1)
y - 38 = 10(x - 4)

Simplify the equation:

y - 38 = 10x - 40
y = 10x - 2

Therefore, the equation of the linear function that models the relationship is y = 10x - 2.
